[Industrial applications]

 The present invention is applied to the case where the electric equipment or members on the power feeding side and the power receiving side are electrically connected by absorbing thermal stress, vibration, positional error, etc. between them or by allowing relative movement between them. It relates to a flexible connecting terminal used. More specifically, the present invention relates to a flexible connection terminal in which terminal blocks made of a conductive metal slab or the like are attached to both ends of a flexible conductor made of a conductive metal braided wire.

[0002]

[Prior art]

 Conventionally, flexible connecting terminals have been constructed by laminating a large number of conductive metal thin plates as flexible parts, or by using conductive metal braided wires with the above terminal blocks attached to both ends. There is. Among these, the connection terminal using the conductive metal braided wire generally has a structure in which the end of the braided wire is inserted into a thick-walled copper tube terminal block and compressed and fixed together. At this time, the terminal portion is compressed at a specified compression rate in consideration of electric resistance, and the compression rate is determined by the cross-sectional area of the braided wire, the width of the terminal block, and the like.

[Problems to be solved by the device]

 However, as shown in FIG. 4, the connection terminal using the conductive metal braided wire as the flexible conductor 1 is used when only one side of the terminal block 2 is in contact with the mating connection member 5 and is bolted. Although there is no problem, when inserting the terminal block 2 into the hole 6 of the mating connecting member 5 as shown in Fig. 3 and pinching the terminal block 2 from both sides with bolts, make sure that the thickness of the terminal block 2 is Must be constant. At present, this is handled by changing the cross-sectional area of the conductive metal braided wire conductor 1 and changing the inner method of the copper tube terminal block 2, but the problem is that it requires time and effort. The present invention has been proposed in view of such a situation, and the conductive metal braided wire is flexible even when the terminal block 2 is inserted into the hole 6 of the mating connecting member 5 and bolted as shown in FIG. It is an object of the present invention to provide a flexible connection terminal that does not require changing the cross-sectional area of the conductor 1 or preparing a plurality of types of terminal blocks 2 having different internal methods.

[Means for Solving the Problems]

 The present invention provides a flexible connection terminal comprising a flexible conductor made of a conductive metal braided wire and a conductive metal thick tube terminal block compression-bonded to both ends of the flexible conductor. The thickness of the terminal block on the mating side according to the thickness of the terminal block. It is characterized in that it has a specified size that fits into the terminal block insertion hole of the connecting member.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings. FIG. 1 is a vertical sectional view of a flexible connecting terminal showing an embodiment of the present invention, and FIG. 2 is a perspective view thereof.

In the figure, reference numeral 1 is a flexible conductor obtained by knitting a metal thin wire into a tubular shape and flattening the metal thin wire, and copper or aluminum having good conductivity is appropriately used as a material thereof. The thickness of the above-mentioned flexible conductor 1 is arbitrarily selected to have a size suitable for current and voltage. Reference numeral 2 denotes a terminal block made of a thick-walled conductive metal tube attached to both ends of the flexible conductor 1 in the longitudinal direction, and the material is appropriate, but preferably the same material as the flexible conductor 1 is used. And

Reference numeral 3 is a conductive metal braided wire segment for supplementing the thickness, which is formed to have substantially the same shape as the compression portions 4 at both ends of the flexible conductor 1. The thickness of the compression portion 4 corresponds to the thickness of the terminal block 2. It is a value calculated by maintaining the size to a specified dimension and calculating so that the specified compression rate is achieved. The conductive metal braided wire segment 3 for supplementing the thickness is not particularly limited as long as it is a braided wire made of a metal having good conductivity, but preferably a braided wire conductor made of the same material as the flexible conductor 1 is used. Good to use.

[Effect of device]

 As described above, according to the present invention, according to the thickness of the flexible conductor, the supplementary conductive metal braided wire segment having the required thickness calculated from the calculation of the compressibility of the flexible conductor is superposed on the end portion thereof. By compressing together and ensuring the thickness of the terminal block to the specified dimension, it is durable with the specified one without changing the cross-sectional area of the flexible conductor or changing the size of the terminal block. A flexible connection terminal having good properties can be obtained.
